Cisco CCNA Routing and Switching

The CCNA is an industry standard certification that demonstrates competency in data networking operation. If you’re interested in a data networking career or wish to advance your current data networking career, obtaining your CCNA is a great way to create career opportunities for yourself. To earn the CCNA Routing and Switching designation, you must either pass both the 100-105 ICND1 Exam and the 200-105 ICND2 Exam or you must pass the 200-125 CCNA Composite Exam.
This path, which contains 19 courses, is built using the Cisco CCNA exam objectives. The path starts with the most fundamental concepts to create a framework, which will be used to understand the more complex protocols presented later in the path. ... Read moreRead less

Introduction to Networking for Cisco CCNA 200-125/100-105

Description

In this course, Introduction to Networking for Cisco CCNA 200-125/100-105, you will examine how basic human communication, like talking in person or on the phone, contains the same fundamental concepts used in moving data across a network. First, you will learn how to examine communication, and determine how to dissect it into components so it can be individually categorized and described. Next, you will learn how to break down communication into components, which will be of great benefit when understanding data networking, as there are many simple protocols which interact in complex ways. To accomplish this you will learn the TCP/IP and OSI models of networking, encapsulation, addressing, as well as what is called "chunks of information" at different points in the communication process. Finally you'll learn about the history and the birth of high speed data communications. By the end of this course, you'll know the OSI Model, TCP/IP Model, and you'll have an understanding of what encapsulation is as it relates to data networking.

Network Layer Addressing and Operation for Cisco CCNA 200-125/100-105

Description

As early as 1985, engineers knew there would be a shortage of IPv4 addresses before the end of the century. Over the next decade, engineers found a very clever solution to the problem, however it created a complex address. This course will go into extreme detail to describe the structure of an IPv4 address and its subnet mask counterpart. To do this, understanding binary numbers becomes very important. We will describe how binary numbers work, how to convert from decimal to binary and back again, as well as see how hexadecimal easily integrates into binary. This may sound daunting, however, we keep the content simple and easy to follow, so it is not overwhelming. After understanding binary and the structure of an IPv4 address, we will examine how to break a single IPv4 network into multiple IPv4 networks, understand the definition of a network address, broadcast address, and a host address. We will the examine how to calculate networks more efficiently using Variable Length Subnet Masking(VLSM), and to wrap up IPv4 addressing, we will take a simple IPv4 network, break it into 2 networks, and then observe its behavior across a router. Once we wrap up IPv4, we move into IPv6, and explain the nuances of this new and obscure looking address. We keep it as simple as possible, so you understand the structure and operation of the IP address, without getting bogged down in nuanced details, infrequently used in IPv6. We will wrap up IPv6 by learning how IPv6 networks are distributed to ISPs, customers, and finally customer sites.
